-# Maintenance Terms
-
-> Last Updated: 27 June 2025
-
-The code, text, and other materials in this repository are provided as-is under
-the terms of the repository's [`LICENSE.md`][0] file, as a gift to the commons
-and the common good. In providing this software as-is, its author(s) admit no
-further obligations from anyone using the software for any reason, particularly
-with respect to:
-
-* Releases,
-* Response time,
-* Change review and integration,
-* Disclosure schedules,
-* Discretionary, proprietary or otherwise secretive communications, and
-* Any other non-contractual obligations or conventions, regardless of their
-  presumed urgency or severity.
-
-Should anyone wish to make a contract with me (Gavin Howard) to ensure that work
-he or she deems critical gets done, the terms are as follows:
-
-* Compute time will be charged at \$25/hr.
-* My time will be charged at \$100/hr.
-* All issues deemed critical by either me or the requester, that also change the
-  source code (anything in `gen`, `include`, or `src`) will require at least two
-  weeks of fuzzing without error.
-	* If errors are found, those hours will still be charged on top of the final
-	  two weeks.
-* All changes will require running the [release script][2] on Linux (GCC), Linux
-  (Clang), FreeBSD, OpenBSD, macOS, Windows.
-* Any hours spent on bugs or code that have been, or are suspected to have been,
-  generated by "AI" will be charged double rates.
-
-Compute time includes, but is not limited to:
-
-* Fuzzing.
-* Running my [release script][2].
-* Running tests and my [release script][2] on macOS.
-
-My time includes, but is not limited to:
-
-* Code review.
-* Reading bug reports.
-* Design.
-* Coding.
-* Any compute time that interferes with my ability to do any other work:
-	* Fuzzing makes my computer unusable, so fuzzing for the 8-12 hours of the
-	  day that I could be working will be charged at \$100/hr.
-	* Same with running my [release script][2] because I run two instances on my
-	  machine and two in VMs at the same time.
-	* Running my [release script][2] or any other compute time on Windows
-	  because Windows blocks me from doing my main work on Linux.
-	* Any other instances of blocking compute time.
-
-All amounts will be billed by, and paid to, [Yzena, LLC][2]. Invoices will be
-provided, including line items for what each hour was spent on.
-
-It is suggested that the following amounts be budgeted:
-
-* At least \$3000 for a non-critical issue or change.
-
-  The release script takes about 10 hours, and I would need to run it once on
-  Linux (and others at the same time) and once on Windows, which is 20 hours.
-  Most of that won't be at the \$100/hr rate, but some probably will be. Then
-  an extra \$1000 for other work.
-
-* At least \$15,000 for a critical issue or change.
-
-  The \$3000 above is the start, which leaves \$12,000. Fuzzing is expected to
-  cost \$11,400 (6 days a week, 8 hours a day, at \$100, the rest at \$25), and
-  rounded up to \$12,000 for good measure.
